If there isn't any pull out table or extension part functioning as a writing space it was probably never meant to be used as a desk. The curved sliding cover (aka roll top?) could hide anything, the glass doors lean towards a more decorative display of somthing. I have seen roll top phone stands, the most common phone desks used to be a low table with a seat on the side. It looks like it's designed for some kind of specific purpose with the open space and curved side on the top right.
